From: Ville Syrjälä Date: Tue, 8 Jul 2014 05:01:52 +0000 (+0530) Subject: drm: Add support_bits parameter to drm_property_create_bitmask() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7689ffb32fa314cc6f128b433b5a285f2699cb70;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm: Add support_bits parameter to drm_property_create_bitmask() Make drm_property_create_bitmask() a bit more generic by allowing the caller to specify which bits are in fact supported. This allows multiple callers to use the same enum list, but still create different versions of the same property with different list of supported bits. v2: Populate values[] array as non-sparse Make supported_bits 64bit Fix up omapdrm call site (Rob) Cc: dri-devel@lists.freedesktop.org Signed-off-by: Ville Syrjälä Reviewed-by: Imre Deak Reviewed-by: Sagar Kamble Acked-by: Dave Airlie Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/drm_crtc.c b/drivers/gpu/drm/drm_crtc.c index 41c7212081b8..2fbee61d632d 100644 --- a/drivers/gpu/drm/drm_crtc.c +++ b/drivers/gpu/drm/drm_crtc.c @@ -3395,19 +3395,28 @@ EXPORT_SYMBOL(drm_property_create_enum); struct drm_property *drm_property_create_bitmask(struct drm_device *dev, int flags, const char *name, const struct drm_prop_enum_list *props, - int num_values) + int num_props, + uint64_t supported_bits) { struct drm_property *property; - int i, ret; + int i, ret, index = 0; + int num_values = hweight64(supported_bits); flags |= DRM_MODE_PROP_BITMASK; property = drm_property_create(dev, flags, name, num_values); if (!property) return NULL; + for (i = 0; i < num_props; i++) { + if (!(supported_bits & (1ULL << props[i].type))) + continue; - for (i = 0; i < num_values; i++) { - ret = drm_property_add_enum(property, i, + if (WARN_ON(index >= num_values)) { + drm_property_destroy(dev, property); + return NULL; + } + + ret = drm_property_add_enum(property, index++, props[i].type, props[i].name); if (ret) { diff --git a/drivers/gpu/drm/omapdrm/omap_plane.c b/drivers/gpu/drm/omapdrm/omap_plane.c index 3cf31ee59aac..aff06e7a4e5f 100644 --- a/drivers/gpu/drm/omapdrm/omap_plane.c +++ b/drivers/gpu/drm/omapdrm/omap_plane.c @@ -317,7 +317,10 @@ void omap_plane_install_properties(struct drm_plane *plane, { DRM_REFLECT_Y, "reflect-y" }, }; prop = drm_property_create_bitmask(dev, 0, "rotation", - props, ARRAY_SIZE(props)); + props, ARRAY_SIZE(props), + BIT(DRM_ROTATE_0) | BIT(DRM_ROTATE_90) | + BIT(DRM_ROTATE_180) | BIT(DRM_ROTATE_270) | + BIT(DRM_REFLECT_X) | BIT(DRM_REFLECT_Y)); if (prop == NULL) return; priv->rotation_prop = prop; diff --git a/include/drm/drm_crtc.h b/include/drm/drm_crtc.h index bfc7235a9c0e..cb4850a2b0c1 100644 --- a/include/drm/drm_crtc.h +++ b/include/drm/drm_crtc.h @@ -1006,7 +1006,8 @@ extern struct drm_property *drm_property_create_enum(struct drm_device *dev, int struct drm_property *drm_property_create_bitmask(struct drm_device *dev, int flags, const char *name, const struct drm_prop_enum_list *props, - int num_values); + int num_props, + uint64_t supported_bits); struct drm_property *drm_property_create_range(struct drm_device *dev, int flags, const char *name, uint64_t min, uint64_t max);
